The Grip Tip or Bar End Lidlox was originally designed in 2006 and patented in 2007 by Matt Mrdeza. It is a really slick and clean small locking device that mounts to the end of your handle bars in place of your stock bar end weights or grip end caps. Lidlox are really easy to install and really convenient to use. Take a look at the Video and also check out all the customer reviews in the webstore. Lidlox customers absolutely LOVE their Lidlox!
